1. Polarity Each battery has a positive and negative terminal.

2. The negative terminal is called the cathode and the positive is the anode.

3. The conducting wire connecting the negative terminal of battery and the metal part of the automobile body is called the bond strap.

4. Do not link positive terminal and negative terminal by conductor, nor spill conductible liquid such as alkaline or acidic solution on or near the capacitor.

5. When the plate was connected to the negative terminal there was no current.

6. Step 2: Run the second wire between the negative terminal and the spare terminal of the light bulb holder .

7. The conduct wire connecting the negative terminal of battery and the metal part of the automobile body is called bond strap.

8. Connect the lead from the cuprous oxide plate to the negative terminal of the meter.

9. We conventionally consider the electric current to flow from the positive to the negative terminal.

10. The blue trace shown in the example is the Low Tension (LT)signal, measured from the coils negative terminal (marked number1).

11. In experiments using EHT for electron gun operation , the negative terminal is connected to earth.
